the Interior, under such rules as he may prescribe, may dispose of
sand, stone, gravel, vegetation, and timber or other forest products, on
public lands of the United States which are under his exclusive
jurisdiction, if the disposal of such materials is not otherwise expressly
authorized by law and if such disposal would not be detrimental to the
public interest. Such materials may be disposed of only upon the
payment of adequate compensation therefor, to be determined by the
Secretary, and only after public notice of the disposal has been given
prior thereto in such manner as may be prescribed by the Secretary.
Nothing in this section shall be construed to apply to any national
park or national monument or to any Indian lands or lands set aside
or held for the use or benefit of Indians, including lands over which
jurisdiction has been transferred to the Department of the Interior by
executive order for the use of Indians.

SEC. 2.

All moneys received from the disposal of materials under
this Act shall be disposed of in the same manner as moneys received
from the sale of public lands.

SEC. 3.

Before disposing of any such materials referred to in section
1, the Secretary shall first give public notice, published in a newspaper
published in the county where such materials are located and if no
newspaper is published in such county, then in the county nearest
thereto, for at least thirty days, of his intention to dispose of such
materials. No such materials in excess of $10,000 shall be disposed of
unless authorized by laws of the United States. The powers granted in
this Act shall cease to exist at the cessation of hostilities in the
present war as determined by the President by proclamation or the
Congress by concurrent resolution and the provisions of this Act shall
not apply where disposal of such materials have been expressly
prohibited by laws of the United States.
